Optoisolators, or optocouplers as they are sometimes referred to, are electronic devices used for separating two circuits by using light. The 6N138#020 is a transistor, photovoltaic output optocoupler which is widely used in industrial, automotive, and consumer electronic applications. The 6N138#020 offers a variety of features which make it ideal for optocoupler applications. This article will discuss the application field and working principle of the 6N138#020 transistor, photovoltaic output optocoupler.

The 6N138#020 is primarily used in applications where galvanic isolation or electrical noise protection is needed. Examples of applications where this optocoupler is adequate include motor control, current/voltage monitoring, data communications, and switchgear. In these applications, the 6N138#020 is used to isolate input signals from the controlling circuits, which helps protect sensitive components from destabilizing ambient electrical noise.

The main feature of the 6N138#020 is its high insulation resistance and fast response time. The 6N138#020\'s insulation resistance is rated up to 1.5kV, which helps protect circuits from electrical shock and reduces the risk of system failures caused by voltage spikes or unexpected signals. Additionally, the 6N138#020 has a fast response time of 600ns (max), which makes it ideal for controlling fast switching electrical signals and data transmission.

The 6N138#020 is a photovoltaic, transistor output optocoupler. This optocoupler features three pins on the side which are used to supply power to the device. The first pin is a cathode, which is used to connect the devices\'s voltage supply. The other two pins are the anode and the base. The anode is responsible for supplying the light output to the optoisolator and the base is used to regulate the devices response time.

The 6N138#020 also features a photodiode and a phototransistor circuit, which are the two main components of the device. The photodiode receives light from the anode, creating a small electric current. This current then triggers the phototransistor, which controls the output signal. This output signal can then be sent to other devices or circuits, depending on the particular application of the optocoupler.

In summary, the 6N138#020 is a transistor, photovoltaic output optocoupler used for electrical isolation, noise protection, and data communications. It is an excellent device for controlling fast switching electrical signals and data transmission due to its high insulation resistance and fast response time. Thanks to the integrated photodiode and phototransistor, the 6N138#020 optocoupler provides reliable, consistent output signals which are ideal for a variety of industrial, automotive, and consumer applications.
